This educator's guide explains basic aeronautical concepts and provides a background in the history of aviation within the context of flight environment (atmosphere, airports, and navigation). The activities in this guide are designed to be uncomplicated and fun. They were developed by NASA Aerospace Education Services Program specialists who have successfully used them in countless workshops and student programs around the United States. The activities encourage students to explore the nature of flight and experience some real-life applications of mathematics, science, and technology. The guide begins with education standards and skills matrices for the classroom activities, a description of the NASA aeronautics mission, and a brief history of aeronautics. Activities are written for the educator and divided into three chapters: (1) Air; (2) Flight; and (3) We Can Fly, You and I. Each activity begins with objectives, education standards and skills, and background material for the subject matter. The activity continues with step-by-step instructions and associated graphics to help the educator guide students through the activity in the classroom. Each activity includes student pages, which are as simple as a graphic of the activity and as advanced as a work sheet. They are meant to supplement the educator's presentation, serve as reminders, and inspire students to explore their own creativity. Activities requiring step-by-step assembly include student pages that present the project in a way that can be understood by pre-literate students. Each chapter ends with a section listing suggested interdisciplinary activities. (ASK)
